Summary

In kong, I have configured key-auth and JWT plugin on my api. In case of invalid credential or invalid token, request fallback to anonymous consumer having request-termination plugin. Hence, request terminates with status code and message configured in request-termination plugin.
Is there a way request-termination plugin terminates the request but still show validation messages coming out of key-auth or JWT plugin.
Issue I am facing is - how do I show invalid grant_type or token expired validations done by JWT plugin.

Steps To Reproduce

1. create an api
2. enable key-auth and JWT plugin on the api
3. create a consumer, create key-auth credentials for it. Also, create RS256 algorithm based JWT credential for it.
4. create an anonymous consumer. Create request-termination plugin for it.
5. Specify Kong UUID of anonymous consumer in config.anonymous field value in key-auth and JWT plugin earlier enabled for the api.

@amitsit06, currently you cannot. We have plans to rework plugins runloop in a future, and authentication is surely something that needs some reworking, and suggestion you made here, makes a sense, so thank you for reporting. Unfortunately at this point there is no answer to that.
